What is the metal thickness of the moldboard?
I just picked up a work truck at a great price. In addition to being good for a work truck it also has a Western unimount 8 foot plow. It's a 1997 F350 XL regular cab Powerstroke whose undercarriage is in excellent condition and has recently had some body panels replaced. The plow functions great, however it's got some rust issues. I believe that this was someone's driveway plow as it looks to be in excellent shape except for one rust hole near the top portion of the moldboard, about where the Western sticker would go. The cylinders all look great and even the frame itself looks good, I just think the plow sat outside too much with too little use.
So for the point of my question. I would like to blast the moldboard and clean up the minor corrosion on the frame. I would like to weld a small patch onto the moldboard where the one small hole is and then paint everything. I don't expect it to look factory new, but I think with the corrosion cleaned up and a couple coats of Western rattle can red and a little buffing I can get it looking downright respectable. So what thickness metal would be appropriate for a small patch on the moldboard? The hole is probably about 2" x 3" in size. It's on a pretty flat section of the moldboard too so it should be a pretty easy patch job. Thanks in advance for the advice.
